Lately CBD methodologies like as CBD96, Catalysis, Fusion, and SCIPIO have been introduced. These methodologies has their own proprietary component reference model. Using proprietary reference model falls interoperability among methodologies. Furthermore it can cause confusion and difficulty for component developers, In this paper, we propose a integrated component meta-model for support consistency and interoperability among component designs. Also, we compare our proposed meta model to existing component reference model by using component's characteristics. We expect that it is easy to add new meta model elements and extends meta-model by using integrated component meta-model.

현재 EJB(Enterprise Java Beans), COM+(Component Object Model+)등의 서로 다른 컴포넌트 참조 모델(Component reference model)을 기반으로 한, 상이한 컴포넌트 시스템 간 통합(Integration)에 대한 새로운 기술들이 제기되고 있다. 동일한 컴포넌트 플랫폼에서 컴포넌트 간 운용은 소스레벨의 결합(Composition)을 통해 이루어진다. 그러나 상이한 컴포넌트 플랫폼의 경우, 유사 도메인 컴포넌트임에도 불구하고 컴포넌트 간 결합은 불가능한 실정이다. 본 논문에서는 상이한 컴포넌트 플랫폼 즉, EJB와 COM+ 컴포넌트 간의 결합 문제를 모델기반의 컴포넌트 변환 기법으로 해결 하였다. EJB, COM+ 컴포넌트 간 결합을 위해 각 참조모델을 비교, 분석하여 구현 독립적(Implementation Independent)인 가상 컴포넌트 모델(Virtual Component Model)과 상호 변환을 위한 구현 테이블(Implementation Table)을 제시하였다. 가상 컴포넌트 모델과 구현 테이블을 참조, 각 구현 모델을 가상 컴포넌트 모델로 일반화하거나 가상 컴포넌트 모델링을 통하여 플랫폼의 구현 독립적인 가상 컴포넌트 모델을 작성하고, 선택적으로 EJB와 COM+로 변환 가능하게 한다. 상이한 컴포넌트 플랫폼으로의 효율적인 모델변환 방법을 제시함으로서 EJB와 COM+ 컴포넌트간의 결합이 가능하다.

As CBD technologies and researches have been matured, component framework as a larger reuse unit than component is being introduced. Especially issues related with adaptation and integration of components in CBD are being raised as a new research topic. The component framework is given as a solution to resolve these issues. However, current approaches don't suggest a sound and comprehensive reference model and development process applying reference model. In order to develop practical and stable component framework, reference model and concrete guidelines are essential elements. In this paper, we propose a generic reference model integrating existing reference models and a design technique of component framework based on it. Especially, we propose concrete and pragmatic guidelines such as how to design component framework architecture's view and style, how to design commonality and variability of component framework, how to design macro workflows among components, and so on. We believe that the proposed reference model becomes basis for component framework development, and the proposed design technique will support reliable and effective development of the component framework.

컴포넌트 기반 개발 (CBD) 기술은 객체 보다 더 큰 컴포넌트 단위의 재사용을 통하여 개발 생산성을 높이는 재사용 기술이다. 그러나, CBD 컴포넌트의 구성요소와 의미를 정의하는 참조 모델이 국제적으로나 산업계에서 표준화되지 못하고 있어 CBD 플랫폼간의 상호연동과 이식성 문제가 있으며, 또한 개발자에게 어떤 모델을 채택해야 할 것인지의 신중한 결정을 요구한다. 본 논문에서는 대표적인 컴포넌트 참조모델들에 대한 정형적 뷰(View)인 메타 모델을 정의하고, 이를 기반으로 기술적인 상호 비교를 제시함으로써 각 기술의 장ㆍ단점 및 특징을 규명한다. 또한, 비교 평가를 통해 모든 컴포넌트가 공통적이며 필수적으로 만족해야 하는 핵심(Essential) 컴포넌트 모델과 최대한 다양한 장치와 구성요소를 가지는 확장(Extended) 컴포넌트 모델을 제시하여 상용 컴포넌트 모델들과의 객관적인 연관 관계 및 각 모델에 대한 정확한 평가를 할 수 있게 한다.

Covid-19 posed a serious threat to public health worldwide, especially in the absence of vaccines or medicines. The only viable strategies to combat a virus with a high infection rate were to apply lock-down strategies, transport ban, social and physical distancing. In this work, we provide a domain-specific component model for crisis management. The model allows for building a plan for managing Covid-19 crisis and use the plan as a template to generate a system specific for managing that crisis. The crisis component model is derived from X-MAN II, a generic component model that we have developed for the aircraft industry

Model-driven and component-oriented development is increasingly being used in the development of embedded systems. When combined, both paradigms provide several advantages, such as higher reuse rates, and improved system quality. Performing model-driven and component-oriented development should be accompanied by a component model and a method that prescribes how the component model is used. This article provides an overview on the MARMOT method, which consists of an abstract component model and a methodology for the development of embedded systems. The paper describes a feasibility study that demonstrates MARMOT's capability to alleviate system design, verification, implementation, and reuse. Results indicate that model-driven and component-based development following the MARMOT method outperforms Agile development for embedded systems, leads to maintainable systems, and higher than normal reuse rates.

This study aims to systematically identify direct and indirect factors that influence labor productivity and to build a model that mathematically quantifies them so as to efficiently manage and increase labor productivity in the construction work. This study was performed based on the productivity model for workers in reinforced concrete construction projects, because it aims to establish a general construction labor productivity model that reflects many factors that influence labor productivity. Using statistical analysis, we found that the components that significantly influence productivity were the worker component, the work characteristic component, the work technique component, the work management component, the equipment & materials component, and the work guide component, while the work delay components did not significantly influence productivity. In addition, a priority analysis was performed based on the components that showed statistically significant effects. The results of the analysis indicated that the influence of work management component and the work technique component is more than that of the worker component and the work characteristic component. The construction labor productivity model that was formulated in this study could be used for the determining the standard productivity during the initial planning stage, so the best strategy for increasing labor productivity could be formulated.

The primary purpose of this study was to investigate the validity of a component model of gender role and differences in children's gender concepts with age and sex. The secondary purpose was to investigate the relationship between children's gender schema and memory as well as preference for gender related task. 181 children were interviewed about gender concepts and gender related tasks. Results indicated that three dimensions of the component model (i. e., gender label-component links, within-component links, between-component links) were significantly related to each other. The mean scores of gender role knowledge and attitude were different with age but not with sex. The results of the regression analysis showed that children's age, sex, and gender role attitude explained both memory and preference for gender related tasks. The component model had better explanatory power than the simple model. The findings of the present study suggest that children's gender concepts are better described in terms of the component model than the simple model and may contribute to a theoretical rationale for gender schema theory.

As an optimun alternatives for the solution of recent software crisis, we have to develop component technologies so as to develop and propagate business components for various domains to industries. For the sake of development of business components, a conceptual architecture which defines a model for component assembly should be prescribed first, and a systematic specification method based on this model be defined, so we can build a system environments for making specifications and development of each component by the consistent scheme. In this study, we propose a domain architecture model for implementing the pUblic component bank as a project supported by the ministry of information and communication, discuss the conceptual model of specification for developing components of storing component bank, specification steps, specification approach for application of business domains and the development results of them.
